Application filed June. 16, 1917. Serial No. 175,123.

To all whom it may concern:

Be it known that I, GUST V .l VOLF, a citizen of the United States, and a resident of the city of New York, borough of ,the Bronx, in the county of Bronxand State of New York, have invented a new and Improved Damper-Regulator, of which the following is a full, clear, andexact description.'

This invention relates to a particular regulator for dampers and has tor an object the provision ot'improved means for operating the damper shifting arm.

Another object in view is the arrangement in a damper of a metallic diaphragm bolted or otherwiserigidly clampedtonthe casing near its periphery.

Another object of the invention is the provision of a diaphragm for regulators which is bulged centrally and corrugated from near the center to near the outer edge.

A still further object in view is to provide a metal diaphragm formed with openings designed to receive bolts provided in a casing, the openings of the diaphragm being so arranged as to receive the bolts of different casings when differently arranged.

In the accompanying drawing,

Figure 1 is a longitudinal vertical section showing the casing of a diaphragm disclosing the invention;

Fig. 2 is a detail perspective view of certain part broken away from part of the diaphragm shown in Fig 1; and

Fig. 8 is a top plan view of the diaphragm shown in Fig. 1.

Referring to the accompanying drawing by numerals, 1 indicates a casing which may be of any desired kind, provided with a top member 2, having a guide 3 in which the rod 4 is slidably mounted, said rod having an enlargement or piston 5 resting on the central section 6 of diaphragm 7. The casing 1 and top 2 may be of any desired construction without departing from the spirit of the invention, said casing top member 2 having openings for accommodating bolts 8, which clamp the casing and top member together with the diaphragm 7, as shown in F 1. The top member 2 is provided with a post 9 which accommodates the pivotal pin or bolt 10, which extends from the arm 11, said arm having any desired number of openings 12 for receiving a chain or other member whereby the arm is connected to the .ti rely from the rod. pm 11 :may pass through the rod 4L and arm 11, the loose motion of the rod 1 in the gu de 3 perm1tting this connection without nterfer ng with the up and down inove- ,mentof the rod.

q'llhe diaphragm 7 is made frommetal and is made comparatively strong to withstand any desired pressure,-butin order to withstand steam pressure and to provide a sufficient up and down movement it is bulged or made somewhat globular as shown in F ig. 1, while the corrugations 15 are provided from near the centrally fiat portion to the flat outeredge 16. It will be noted as the steam passes into the casing near the opening 17 it will pass through this to the passageway 18 into the space or chamber 19 immediately below the diaphragm 7 and consequently act on the diaphragm so as to move the same upward and the arm 11 attached thereto. The diaphragm 7 by reason of bulged construction must move a distance to reach a straight line and then if necessary can move still farther on to a position substantially opposite to that shown in Fig. 1. This will allow ample movement for causing the arm to actuate the proper members for closing the drafts of the furnace to which the device is connected, whereby the steam pressure will automatically be reduced. v

In order that the diaphragm 7 may be secured to the casing 1 regardless of the arrangement of the apertures for the bolts 16, the section 6 of the diaphragm 7 is provided with a number of apertures 20, there being shown four in Fig. 3, and-a number of arc-shaped slots 21. By the arrangement of these apertures and slots as shown in Fig. 3, any number of bolts may be used from one up to eight as indicated by the lines 22, 23, 2-1, 25, 26 and 27 with the exception of possibly five and seven, as either of these odd number of bolts would not provide an even clamping of the edge of the diaphragm. Usually regulators of this character are provided with tour or six bolts evenly spaced, but in some extra large regulators eight bolts are used. By providing the apertures and slots described the same diaphragm may be used with diflerent casings and be readily bolted in place without the provision of specially provided bolt holes. It will be of course understood that the diaphragm 7 may be made large or small and of any thickness as Well as of any metal, preferably brass or some noncorrosive is used.

In order to provide a tight connection at the periphery of the diaphragm a gasket 28 is provided, formed of fiber, asbestos or other suitable material, such gasket being held in place permanently by turned up spurs 29, as shown in Fig. 2, which spurs are part of the material pressed out of the slots 21. By thus providing a gasket and means for permanently securing the same in place the diaphragm is always in proper condition for being instantly applied to a casing. Heretofore diaphragms-have been made principally from rubber and quickly Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

becomeworthless by reason of the action of the steam and water contacting therewith. The use of rubber has been found desirable as it lends a larger movement of the rod 4 which is not provided in ordinary diaphragms which are positioned in a straight line across the casing 1. The useof a diaphragm extending straight across the casing 1 and held in position by being spun around part of the casing is known, but arrangement of a metal diaphragmin a casing with bolts as shown and described has not been known, nor the provision of a bulged diaphragm with corrugations.

What I claim is: i

In a regulator of the character described, a diaphragm therefor comprising a metal sheet having a fiat peripheral section, said flat peripheral section being provided with a plurality of apertures, and spurs extending from some of said apertures, and a gasket arranged agalnst said section held in place by said spurs.
